Damage Simulation of cable of long-span concrete cablestayed bridge

摘要：

　　Stayed cable is a key part of the force system in terms of cable-stayed bridge,its safety performance can be influenced by damaged cable.In this paper,the reduced effective area method 1 is used to simulate the damaged cable and both its location and degree are identified by observing the changes of cable tension.When the effective area is reduced by 10%,30%,50%,the influence of cable loss on mid-span deflection is invested.The damage simulation of cable is carried out by taking the Sutong bridge as the background.The results indicate that it is realistic and possible to simulate the cable loss by using the reduced effective area of cable.Furthermore,the deflection changes of main span is greater when the damaged cable is farther away from tower.
